Patent AT-A42497-A (AT)
IPC: C21B13/00
Filed: 1997-03-12
Abstract: A process to optimize the reduction process with a given quality of ore. The reduction gas 7 is analyzed by means of gas sensor 1 and is separated into two partial flows. The throughput of the partial flow which is oxidized is regulated by a regulation valve 3 and is then sent to the burner 4 where it is oxidized. The other partial flow of the reduction gas is regulated by a regulation valve 2 according to the required amount of gas in the shaft and is thereafter brought to the required temperature in the heat exchanger 11 and mixed with the oxidized partial flow of the reduction gas. The gas components are determined by a gas sensor 13 and, when necessary, a gas delivery 14 is adjusted according to mathematical formulations. This makes it possible to run the reduction process in the direction of its stoichiomeric optimum using a given quality of ore. A further advantage lies in the fact that the reduction gas can be heated to a desired temperature while maintaining a very low oxidant portion in order that the gas analysis can be adjusted in wide ranges.

Abstract: A method for storing respiring produce, particularly bananas, during ripening is disclosed. The method allows bananas to remain in the ripened condition for an extended period of time while, at the same time, having improved sweetness and taste characteristics. In addition, the method does not require separate handling and repackaging of the bananas between the starting of the ripening process and storage/shipment of the bananas. In this method, ripening is initiated by inserting additional gas into the banana package, such that the gas medium comprises from about 2.0% to about 5.0% oxygen, from about 5.0% to about 15.0% carbon dioxide, from about 0.8% to about 1.5% ethylene, the remainder of the gas medium being predominantly nitrogen, for a period of from about 0.5 to about 5 seconds. The composition of the gas medium in the package is then adjusted such that the gas medium has a ratio of oxygen to carbon dioxide which meets the following conditions: (20.94−B)/C=from about 1.8 to about 3.8; wherein B is the percentage of oxygen in the gas medium, C is the percentage of carbon dioxide in the gas medium, and, further, wherein the percentage of oxygen in the gas medium is from about 1.0 to about 6.0, and the percentage of carbon dioxide in the gas medium is from about 3.0 to about 10.0.

Abstract: An apparatus and process for spraying liquids wherein means are provided for subjecting liquid emerging from the sprayhead (1) to an electrical field sufficiently high for the liquid to be drawn from the sprayhead in the form of one or more filaments. The filament or filaments become unstable and subsequently break up into droplets. A stream of gas is caused to flow through the region of the high electrical field, the gas flowing in a direction parallel or substantially parallel with the direction in which the liquid emerges from the sprayhead. Droplets are thus removed from the region and a build-up in space charge is reduced.

Title: Improvements in or relating to textile spinning machines
IPC: D01H1/06
Filed: 1947-01-02
Abstract: 644,307. Textile spinning machine. LOVINFOSSE, L. DE. Jan. 2,1947, No. 128. [A Specification was laid open to inspection under Sect. 91 of the Acts, April 5, 1947.] [Class 120(ii)] A textile spinning machine, in which yarn is wound on one end of a revolving spindle by a cop builder having an internal substantially conical surface and in which twist is simultaneously imparted by a guide member mounted on a ring having a reciprocating movement and following the rotative movement of the cop builder, has at least two vanes provided on the end of the spindle, these vanes extending along a length substantially equal to the length of the cop builder. A roving 4, Fig. 1, is passed from a delivery roller 2, over the hooked end of a rod 14, which is tensioned by a spring 16, to a guide tube 9, from which a hollow block 7 is suspended. A slit 20, Fig. 2, provides an exit from the block 7 for the roving 4, which is then led through a guide member 22 on a rotatable ring 23 having a vertical reciprocatory motion, so that yarn is traversed as it passes through a slit in the block 7 to be wound on a spindle 12, provided with upstanding vanes 13. The block 7 and tube 9 are rotated by gears 31, 32. As yarn builds up on the vanes 13, it makes contact with the sides of the bored interior of the block 7 and continued winding of the yarn causes the package being formed to slide gradually down the spindle 12. A disc 30, Fig. 1, slides on the spindle 12 and may be arranged to brake the downward movement of the package. The spindle 12 is driven through gears 55, 56, Fig. 7, gear 55 having a key and slot connection with the spindle. In order to doff a spindle, a lever 70 has a projection 73 upon it released from contact with a gear casing 63, whereupon the spindle 12 falls so that its upper end is freed from the block 7, whereupon an arm 87 may be raised and a lever 84 drawn forward to tilt the casing 63 and spindle 12 to a position in which the yarn package may be slid off the top end of the spindle. A bar 81 is arranged to displace all the levers 70 on one side of a machine simultaneously. In order to raise the spindles to spinning position, a common lifting bar 75 is lifted by a pedal 79 connected to the bar by a cable. When starting a fresh yarn package, it is necessary to modify the speed of the spindle 12, or of the block 7. This is achieved by shifting a belt on a pair of cone pulleys by means of a ratchet and pawl mechanism actuated by the delivery roller shaft. Movement of the belt ceases when the cop chase is completed. The speed of the delivery rollers 2 may be varied manually or mechanically. The Specification as open to inspection under Sect. 91 comprises also replacement of the disc 30 by a conical member forming a base for the package and the omission of the vanes. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to ultrasonic tomographs
IPC: A61B8/14
Filed: 1962-01-05
Abstract: 963,928. Ultrasonic inspection systems. G. A. D. GORDON. Oct. 22, 1962 [Jan. 5, 1962], No. 585/62. Heading H4D. In an arrangement for detecting the configuration of a concoaled surface which reflects ultrasonic waves (e.g. in medical diagnosis) an ultrasonic probe 1 is oscillated about axis XY (normal to the probe beam) and additionally, is moved in a circular or part circular path, the centre Z of which is deemed to lie on the concealed surface. The circular motion is effected by means of two drums 10, 11, the latter, driven by electric motor 14, being coupled via a flexible band 10<1> to drum 10 which is provided (at different radial distances from the axis X<3>, Y<3>) with rotatable pin-carrying discs 18, 19, 20, the pins of which cooperate with holes in a flange 17 attached to a head 4 which, together with a head 5 (similarly mounted on similarly positioned rotatable pin-carrying plates 24, 25, 26 on drums 11) and connecting members 7 form a driving and support means via connecting members 6 for a head 3 carrying the probe 1. The radius of the circular motion of the latter may thus be altered by positioning the heads 4, 5 on selected, corresponding pairs, of the pincarrying discs. The oscillatory motion of the probe about axis XY is effected by an electric motor 27, the direction of rotation of which is periodically reversed by a cam-operated switch and the motion of which is transmitted via a link 29, disc 30, shaft 31 and link pairs 34, 35, 36 to pin-carrying discs 18, 19, 20 and thence via the flange 17, pulley 16, flexible band 15 and pulley 2<1> to the probe support 2. The apparatus utilizes the pulse echo technique and the echo pulses are displayed on a cathoderay tube 42 (also Figs. 3 and 4, not shown), which is mounted on disc 30, offset from the centre, so that the tube effects the same motion as the probe. A camera 45 may be employed to photograph the screen of tube 42.

Title: Improvements in or relating to vapour vacuum pumps
IPC: F04F9/00
Filed: 1933-01-09
Abstract: 413,273. High vacuum injectors. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and GALLIZIA, E., c/o General Electric Co., Ltd., Witton, Birmingham. Jan. 9,1933, No. 711. [Class 71.] A mercury &c. vapour vacuum pump is pro - À vided with means influenced by pressure differences between different parts of the pump and actuating an electric device for indication or control of the state of the pump. Fig. 1 shows a pump in which the circuit of the electric device comprising a relay coil 9 and a current source 10 is completed by contacts at the mercury surfaces in the boiler and in the condensation return tube 4, the circuit being broken on failure of the pump, causing a fall of the mercury in the tube 4, or on depletion of the mercury in the boiler. The boiler may constitute the secondary of a transformer, being thus heated by eddy currents, or it may be otherwise heated, e.g. as described in Specification 380,471. Fig. 2 shows a modification, in which variation of the normal level in the tube 4, due to variation in the amount of mercury in the boiler does not impair the electrical control &c. Two contacts 12, 13 are situated at different levels in the tube 4, and corresponding contacts 23, 24 at the boiler levels in a tube, the latter contacts being connected respectively with coils 21, 22 attracting a moving contact 19 towards fixed contacts. The circuit through the battery 128 is broken if the boiler level falls unduly, the contact 19 then returns to mid position and means 31 in an electric circuit effects a warning or control. In a further modification, coils surround the mercury surface in the condensation tube and at the boiler level and their impedance is varied by magnetizable floating members ; the coils form arms of an alternating current bridge, and lack of balance is detected by a double wave rectifier actuating control relay. The coils are mounted so as to move together, one coil having an ammeter and the other a balancing impedance ; by noting the minimum meter reading, the boiler level is determined ; alternatively a compass needle may be used for this purpose. Alternatively, a series of contacts in the condensation tube and near the boiler level are connected with two arms of a direct current bridge, the relay coil being arranged across one diagonal. The relay may close the main valve of a rectifier being evacuated, or may control delivery or abstraction of heat to or from auxiliary heating means for the boiler. An auxiliary reservoir may be connected with the boiler to control the level of mercury.
Patent GB-462073-A (GB)
Title: Improvements in and relating to the production of artificial fibrous products
IPC: D02J1/22
Filed: 1936-01-08
Abstract: Artificial filaments from solutions of cellulose or cellulose derivatives are subjected to a gradual continuous stretching during the whole or a great part of the time required for complete formation between the spinning nozzle and the bobbin, centrifugal box, belt conveyer or other receiving member.  The filaments are stretched by 40 per cent or more of their length. The gradient of stretching is related to the speed of coagulation which is determined by the composition of the spinning solution, state of maturity, and the composition of the coagulating bath. The filaments may be converted into short fibres.  The duration of the stretching operation may be 15--60 seconds and the total stretch may be 40--80 per cent.  The process is particularly applicable to the spinning <PICT:0462073/IV/1> <PICT:0462073/IV/2> of viscose.  Apparatus for effecting the stretching may comprise a system of rollers mounted on a support revolving about an axis, the rollers being arranged to form a support for the thread in the form of a frame of truncated conical shape, the rollers rotating as a whole and also separately each about its own axis.  The rollers may be cylindrical, conical, or of curved profile, so as to allow the speed of stretching to be varied linearly or otherwise.  As shown in Figs. 1 and 3, the thread f in its initial state of formation is wound in helical turns round the frame formed by a plurality of rollers a projecting from a drum A.  The end pins 11 of the rollers are driven through helical gearing from a central gear-wheel 15 which receives a rotary motion in the same direction as the drum A but at a slower speed.  Wheel 15 is keyed to spindle 16 rotating within the hollow spindle 3, to which it is geared through wheels 17, 19, 20, and 18.  The rollers a may be covered with rubber. Drum A is driven from a shaft 10 through pinions 8, 9 and 5, and the toothed ring 4.  The individual rotation of rollers a causes the thread to be forwarded in helical turns and the increase in diameter of the frame from the receiving to the delivery end results in a progressive stretching of the thread.  An alternative device consists of a frame formed by a number of rollers, the axes of which are arranged according to the generating lines of a cone, the rollers having helically grooved surfaces, and being rotated once for each revolution of the frame. In an example, viscose is extruded into a sulphuric acid-sodium sulphate bath, and the filaments after travelling a short distance in the bath are taken up on the device described above, 70 turns equal to 38 metres being wound on and stretched for 40 seconds. They are then passed on to a winding device.
